11. How much more does a gallon of sea water weigh than a gallon of drinking water?

12. Which weigh more, 1 gallon of oil or 2 gasoline? How much more?


​

Answer 1

10 : 4×6.664

= 26.656

11 :  8.58 - 8.33

= 0.25

12 : weight of 1 gallon of oil = 7.497

weight of 2 gallons of gasoline = 2 × 5.664 = 11.328

11.328 - 7.497 = 3.831

Hence, 2 Gallons of gasoline is heavier than 1 gallon of oil by 3.831 liquid pounds.
